IPv6 App Store Rejection

Question

Our update has been rejected twice today for ipv6 network connectivity issues. Our networking code has not changed between the previous release and this current release.

Answer 1

my app is rejected two times on app store. They give a error to twitter login on iphone having os 11.4. The main issue we have because of callback url of twitter, which is not set on developer account of twitter. when i set callback url on developer account of twitter. It solves my issue. When we dont set callback url on developer accountof twitter that time twitter login is successfull when device having twitter app. but in case of absence of twitter app on device gives forbidden error 403.

So Setting callback url overcomes my problem and app is accepted.

Thank you
